Masamichi Yabuki Stops Felix Alvarado In 12th To Retain IBF Belt

Masamichi Yabuki, the defending IBF flyweight champion, and Felix Alvarado, the former IBF junior flyweight titleholder, gave Tokoname a fierce, unsentimental world title fight that ended the way Yabuki seems to prefer it, with the challenger on the floor and the referee already reaching a conclusion. In the ABEMA pay-per-view main event at Aichi Sky Expo on Saturday, Yabuki dropped the Nicaraguan twice and stopped him at 1:59 of the 12th and final round, retaining his belt in front of a crowd that did not come for a chess match and did not get one.

There was no feeling-out process. Alvarado came to punch, and early on, he found room for straight right hands, the kind that carry through a guard if the timing is right. Yabuki met him with the sharper work, tighter combinations, and quicker counters, and by the second round, he had already marked the pace, whipping in hooks and body shots and even knocking Alvarado’s mouthpiece loose with a left hook upstairs. It became a mid-ring scrap more often than either corner would have admitted to wanting, but Yabuki’s accuracy gave him the cleaner edges, while Alvarado’s responses were brave and busy rather than decisive.

Alvarado’s best spell came when Yabuki’s early snap dipped, and the challenger, still fresh, began to crowd him and force exchanges. Around the fourth and into the fifth, Alvarado’s pressure made the fight feel less one-sided than the opening rounds suggested, simply because he was there, chest first, punching and refusing to be waved off by the champion’s reputation. But the debt for those early rounds stayed on his account, and when Yabuki found a second wind in the sixth, the fight swung back in a more permanent way. He began to meet the rush with left hooks, then went downstairs with intent, and the champion’s body work took air out of the challenger’s attacks until Alvarado was backing up for the first time.

From the back half on, Yabuki looked like a man who had solved the rhythm. He worked behind the jab, mixed in uppercuts, and kept hooking to body and head, the sort of steady punishment that does not always produce a single dramatic moment but leaves the other man a fraction slower each round. Alvarado stayed willing; he managed to get inside often enough to work, and he did land body shots of his own when he could wedge Yabuki onto the ropes, but the sting that was present early was visibly fading. Down the stretch, the uppercut became a recurring problem for him, arriving after one twos or as a counter when he tried to force the action, and by then, he was also dealing with a cut outside his right eye.

The finish came in two stages, and the first was the warning. Late in the 11th, Yabuki finally put Alvarado down with a left hook, the kind that lands short and heavy and makes a man look at the canvas as if it has betrayed him. Yabuki could have coasted, but he went out in the 12th hunting the stoppage, stalking Alvarado as the challenger moved and tried to survive the last three minutes. A left hook to the body opened the door, a jab held it, and then a big right hand to the chin dropped Alvarado to all fours. Referee Katsuhiko Nakamura counted, but the decision had already been made: the visitor would not be allowed to suffer unnecessary damage. For Alvarado, it was a rare and decisive end, his first stoppage loss after a long career, and for Yabuki, it was another reminder that his late career run at the weight has been built on pressure, precision, and the certainty that if you stay with him long enough, the last round may be the worst one.
